AA glycosidic bond
BA hydrogen bond
CAn ester bond
DA peptide bond
Answer & Solution
Correct answer: A. A glycosidic bond
1. Two monosaccharides join by a dehydration reaction that releases one water molecule.
2. The covalent bond left behind between the two sugars is a glycosidic bond.
3. Peptide bonds join amino acids and ester bonds attach fatty acids to glycerol, so neither forms here.
4. A hydrogen bond is not covalent, so it cannot be the bond that builds the polymer.
